Hi guys- I picked up my new Glock and took it for a test drive today. I shot about 200 rounds of WWB 230. I hadn't fired a .45 before. My other handgun is a 9mm Glock 17. The only mods on the sf are Tru-glo fiber optic/tritium sights and an extended mag release. It's very easy to shoot, not much different than the 17. There is more recoil, but it's not a problem. The grip is going to take time to get used to. My hands are medium/large. It feels like I'm not holding the gun securely enough (compared to the 17), but I'm accurate with it, so maybe I'll get used to the feeling. My little finger kept getting pinched when the gun fires. I've read about that in other reviews. It didn't hurt, but I noticed it. I put on shooting gloves after the second magazine. Three times, I had trouble inserting a mag into the gun. I inserted it in the usual way and gave it a tap, but it didn't seat. If I whacked it harder, it would seat. This was with a full mag of ten rounds. It happened with two different mags, but not all the time. Maybe things are just stiff and tight right now, and will loosen up over time. I've read that some guys have had problems with the brass being ejected back into the face. This happened one time. Two other times, the brass hit my cap. I don't know what's up with that. Some reviews have reported it happens all the time (some problem with the ejector?), but for me, I was struck in the face only once out of 200 rounds. Odd. I like the gun and am looking forward to more range time with it.
