I have used and will again as soon as it becomes available is the Michigan made ( remanufactured ) Fenix 9 mm 115 gr. FMJ ammo. It burns well, the price is right and no functioning problems.I have used both the147gr TMJ Speer and the 150gr TSJ Federal Syntech in a PPQ M2 and a CZ Shadow 2 with GREAT results. Both are well below subsonic (985 & 890 fps respectively) and recoil is significantly less that typical 115 or 124 graing rounds. I'm looking for a less powerful recoil spring for the PPQ that should reduce recoil even more.
In my CZ, I am using a 12 lbs recoild spring (factory spring is 16 LBS) and it work well.
Also, the advice from grumpy1 about lube is spot on!
I am far from an expert. But I do own several 9mm pistols (including a poly Q5) with barrels from around 3 to around 5 inches. I prefer shooting 147g FMJ at the range, and I carry the 147g JHP. In my experience they are a tad softer shooting than the lighter, faster bullets. Also, at the range I mainly shoot (7-10 yards), the heavier, slower bullet seems to print closer to my POA. That could just be me, so I can't say it's always true for everyone. I have shot a lot of 124g ammo, and I have noticed very little difference between it and my preferred 147g ammo. I have not shot 115g ammunition except maybe a dozen or so rounds in each pistol just to check functioning with a lighter bullet.I have some 147 Speer lawman and some 150 grain federal synthetic and i was wondering if the walther q5 match shoots these well? Im a bit of a newb when it comes to guns so sorry if this is a remedial question
