Replaced my pin last weekend so was eager to hit the range. This was only my second time out and started with about 50 rounds through my Glock 23 then moved to my XD sub .40 and got one mag down range before cease fire. I changed my target and here are the results: 50 rounds @ 15 yards. It could have been tighter but I am pleased. I had zero misfeeds or failures to lock open like my first time out. I was using American Eagle 165 grain for my practice round. It was a great day!
