I doubt the failure to lock open was ammo related. Dunno.
No sorry, didn't see that info. the failure to lock back issue in my experience was usually mag related. But who knows? Maybe the S&B has a couple sketchy rounds. I've been shooting S&B a ton and have not had a single failure. (PDP Compact 4")@gairman I did not post the fact that I changed the mag springs to stronger ones. I don't know if you've been following the FTF and FTLBS threads.
In most PDPs, any conventional JHP is going to be reliable.I've seen several suggestions for JHP. Are there any less expensive names that are reliable? I'd say full proof, but I've tried S&B 115 grain and had two fails to lock back after last round in same mag. Once w/ 18 rds, once w/ 17. I Haven't been out again and only bought 2 boxes. Fiocchi, ammo Inc, PMC. Basically, anything that comes in 50 rd boxes for around 40 cpr or less. Thanks
P.S. I'll probably get posts saying, "Don't be cheap, it's your life." But why sell this stuff if the expensive stuff is the only reliable stuff out there?
I have a PPS M2, not a PDP. The only bullets mine fusses with are Hornady Critical Defense. It's a go to for some, soft shooting and accurate. But I don't trust it and it sure ain't cheap. Really like their XTP's, though.In most PDPs, any conventional JHP is going to be reliable.
Given all you've posted about the different problems you've encountered though, it's tough to make a recommendation. It's impossible to know what is going to work reliably in your seemingly problematic pistol.
You best course of action might be to return the gun to Walther and have them make it right.
Once that is done, the world is your oyster as far as choosing hollowpoints for your gun.
