Sig Sauer P239.... I have 2 barrels/springs, 1 in .40 and the other 9mm- both on the same frame.
Only in .40 and only with certain ammo it doesn't hold open on last shot. I have a 9mm barrel/spring (Bar-sto) which seems to work fine with 115 and 124 9mm in several different brands. No problems in 9mm.
In .40, however, Using Golden Sabers and American Eagle 165 grain after the last round the slide closes though the hammer is back. Happens with 2 different mags too. Using the PMC Bronze it works OK- also 165 grain.
My guess is that the PMC is hotter allowing the frame to catch, does that sound right? Any other ideas?
.40 is new to me, I know some calibers are designed around certain rounds and I'm thinking maybe I should just try the heavier or lighter loads if .40 was kind of built around a specific load.
