Were you running a comp? My gun was fine with the 18lb factory spring, but adding a comp is what started all the problems.I swapped out my 18lb recoil spring with a 15lb one. Zero issues with bulk range 115gr ammo.
Also, Brownells is selling the frames for $110 each shipped after coupon, so I've gone ahead and bought a 940v2 and a 940SC... the 940SC is more aspirational, given the state of the G26 after-market.
