A 10mm like a 22?? No...this is not a G20 I'm talking about.
I put the Pearce bases on my mags and have shot it more and my groups are shrinking @25yds... max IDPA distances where I shoot. I can routinely hit the 6" plates and pep poppers, now. I'm MUCH happier with it. (15yd slow fire results attached) BTW, I will trade my custom-made 'bad guy' targets for Large Pistol Primers..
IMHO, the G29 is a unique pistol when shooting real 10mm loads 100+ rnds / session.
At first, It felt like I was shooting a .454 Derringer! I'm liking the challenge.
Improvise, adapt, overcome...
