I acquired a Walther .22 target rifle that closely resembles a KKM but only weighs a little over 8#. It appears to have an adjustable trigger but it is accessed from the left side of the stock just above the trigger guard, not through the trigger guard bow.. I can't find any information on adjusting this trigger and am asking that anyone who knows what the designation of this rifle is and who is familiar with this model to advise me as how to adjust the trigger. I cannot see down into the hole and can't even tell if an allen screw driver or a flat blade screwdriver is required.

Andmars, thanks for the reply. The rifle is similar to Rifle 1 on page 1 but the difference lies on the left side which is not illustrated. It is obviously some variant of the KKM. On the left side above the trigger there is a hole which I found to provide access to the trigger. Since it is too narrow to see down into the hole I have pulled the action out of the stock to see what is going on. The hole led to a screw in the trigger assembly and requires a thin flat-blade screwdriver. The trigger assembly is light years away from a KKM trigger. It is simplicity in itself, comparable to the old Winchester M67-era triggers which were not adjustable. If I can find a tutorial on posting pictures I will do that. I think the procedure for posting pictures is the same as for RimfireCentral so I will try that procedure if I can't find a tutorial on this website.

Okay, here ya go, hopefully I can upload the pictures. The first two are full length left and right side views of the rifle, the third is a closeup of the left side of the action area showing the trigger adjustment hole and the sling swivel base, fourth is of the right side of the action area and the fifth is the trigger. Note on simple it is compared to a KKM trigger assembly. I took It to the range today and boy, will it shoot. Unfortunately it showed a pronounced preference for R-50 and Special Match. I would have preferred much cheaper brands but what the heck. The trigger is heavy but smooth and breaks cleanly. Maybe if someone responds with info on how for me to keep from fouling up the trigger trying to adjust it I can lighten it somewhat.

That is identical to my KKJ and i don't believe that screw is an adjustment, its simply just the pivot point for the trigger.

One thing to check is the two rollers that run along the top plate, make sure those turn freely as mine had seized up from old hardened grease inside them. Once i freed them up and lubed them the trigger action was silky smooth.

I also tried RWS R50 in mine and while it seemed to perform well i still had the odd flyer which you could audibly hear having a softer or stronger powder load. The best ammo i found for my KKJ is SK Standard Plus, half the price of premium ammo like R50 or Eley Tenex but every bit as accurate. It also found it more consistent than R50.

Your question was very serendipitous. I normally would have been reluctant to pull the action out of the stock only to take a picture but I had just decided to replace the present scope on this rifle with a Leupold 36 I have on hand so I would have had to zero the rifle again anyway. Might be Sunday or Monday before I can do so as I have grandchildren here for the holidays and they take priority over everything else.

Well, the kids have gone back home to Raleigh and Atlanta and the silence is deafening.

I'll try to answer two posts in this one.

Andmars, attached are picture of two sets of targets I fired with both R50 and Special Match. All targets were at 50 yards. The first picture is of the target I shot a few weeks ago the first time out with my then new-to-me SBR. The second picture is of the same ammunition which I shot 11/16 with my new-to-me KKJ (?). There is no doubt in my mind that the smaller on each target was a one-of and not likely to be repeated. But when you are 81 it is very heartening that I was able to shoot these groups. The target in the lower left is the demo target that came with my SBR, being as you know 10 rounds of R-50 at 50 meters from a mechanical rest. Gives me something to strive for.

Aris, I am afraid I did not do well in the pictures of the trigger. A am a rank amateur when it comes to photography and could contrive no way to get adequate lighting on the subject. Hope they are sufficient to answer your needs.

Very nice groups, nothing to complain about there :)

Since my last post i have had reason to disassemble my KKJ, photo of trigger group attached. Apart from the subtle difference in the trigger shape you can see the mechanism is identical, and non adjustable unfortunately.

Cheers,

Mark

Mark, thanks for the pics. It is obvious that you were right on the money in identifying my KK as a KKJ. I have seen pictures of Walthers identified as KKJs that were entirely different configurations, some target-style and others sporter styles. It is hard to be precise in identifications when there are no reference books with pictures and no identification stamped on the rifles. Much simpler with Anschutz due to the plethora of information available in print and on the internet not to mention factory assistance. Want to go to the range but the weather for the next few days will be poor, mainly due to predicted winds of 10-12 knots or so and heavy rains through Wednesday.

Ok seems i need to eat some humble pie. I just tried to remove that pivot screw holding the trigger on to find it isn't a screw at all, its a concentric adjuster :eek:

As you rotate it the trigger moves higher and lower in the arm, which in turn increases or decreases the amount of sear contact. Fully adjusted to the up position gives you a crisper break point with less trigger travel, and adjusted fully down gives you a longer trigger travel and a slightly heavier trigger action. Adjustment is as simple as rotating that screw 180 degrees from one extreme to the other.

I set mine fully up and it has a much crisper trigger release, also passed the bump test so its perfectly safe, but i recommend you verify that on your own rifle after adjustment.

I have attached two pics showing each extreme of adjustment, note the position of the sear arm vs the barrel and trigger.

I think I've died and gone to heaven! What a great help your post is! Your explanation and pics really help. I had the rifle out last Thursday and while it shot very well the way it was I felt that a few times the groups could have been a lot better if I had the trigger better adjusted. On a number of groups it seemed that it was never going to fire and I feel I became impatient with the fall on some of those groups and forced the shot, much to my immediate regret. I had never heard of a concentric adjuster so feel that it is something that is not common here in the States on domestic actions. I had planned to go to the range tomorrow but the weather guessers are now calling for temps of 38-40F and winds of 8-10 knots so I'll have to wait another day. Actually, that is to the good as now I can open the rifle up and make the adjustments you demonstrated. Maybe, despite the total lack of any help from Walther, we can learn how to max out the accuracy of the units. Thanks again and I'll keep you posted on how things work out.:D

Your rifle isn't a KKJ - J stands for Jagd- but a KKM. Early KKMs had the trigger based on the KKJ, then they changed to a match trigger with fixed trigger blade before they revised it again with the trigger that has the blade adjustable for length.

The receiver cut outs for the trigger assembly are different and so are the locations for the sears and the firing pins, making parts replacement a nightmare.

Andyd, is your last post regarding the KKM/KKJ intended for me or for Andmars? I have not yet found a definitive description of the rifle I have so do not know if it is a KKJ, KKM, or what. It appears to be something other than a pure target rifle due to the presence of sling swivels bases and lack of the usual more sophisticated trigger found on target rifles.

You have an early KKM. The slingswivels pre-date the UIT rules and were for a shooting strap, rather, than a sling to carry the gun.

The first KKM's were based on the pre-war KKJ, as that pre-war design was ready when Germany was allowed rifle production again.

Anschutz followed suit with the Anschütz 54 that was developped by Gehmann. Both designs were developped out of a reduced size Mauser bolt, as commonly seen in the DSM.
