Picked up a Taurus G3C yesterday, for a sub-300.00 pistol I'm quite impressed. Comes with 3 mags, Glock sight compatible, and trigger pull is quite competent. Took it out for a test drive and it is dead on with factory 115 grain FMJ. Tried my usual 3.8 grains HP-38/.357 134 grain RNFP load that my Glocks like and accuracy was not as good, also saw some mild leading in the barrel. Function was 100% with either load though. Upon cleaning I found this thing has a really tight throat. I recently bought a bunch of Berry's .357 plated truncated cone slugs and they chamber just fine in my Glocks OEM and Storm Lake barrels even seating them out really far, like 1.070. I found that they have to be seated to where the case mouth is even with the beginning of the ogive for them to chamber in the Taurus, like 1.005, which sounds like a recipe for high pressure to me.
Factory rounds chamber no problemo so I think this is just how these guns are made and the accuracy is quite good. So, should I ship the barrel off to Doug Guy for some of his magic? Or try a few hundred jacketed slugs to see if it will break in. I'm planning to use exclusively lead and plated in this pistol.
