Not as much as I probably should. I'll do the drill about every 4'th session. Not nearly as consistent as I'd like. Only good out to about 10 yards and at 15+ yards, that takes some concerted focus. The 1911's are ok since the triggers are so nice. The DA 9's ugh. Sometimes I do surprise myself but again, not as consistent. Interestingly the other day I went into a shop to sell off some coins. The owner carried a Beretta 92 on the right hip and on the left was a Sig 238. Had me thinking about this thread.
