Hi Gunhacker,
Yes I was surprised as well. I was not alone though. Out of 16 of us qualifying last year with full size duty pistols and compact off duty/BUG guns, in the same caliber, six of us who regularly shoot in the top ten, shot perfect scores with our compacts.
In fact all six of us had identical scores 98 day 98 night with the full size duty pistol. 100 day 100 night with the off duty compact.
The qual is 50 shots day, 1 to 25 yards and 50 shots night, 1 to 15 yards.
While discussing it during the smoke and joke afterwards, we came to the conclusion that the shorter slides were an advantage in point shooting as was the shorter distance to the front sight in forming a snap sight picture. Some also opined that the added effort needed to shoot a small pistol well, forced us to focus on the basics harder - thus improving our performance. Dunno..............
There have been threads about this.....phenomena...on other boards. Apparently lots of shooters are more accurate with their compact 45's than with their full size guns.
I'd be interested in y'alls opinions on this topic. This thread is as good as any to discuss it.

Regards 18DAI
Good luck Stu Honea!!
