Hey guys, My name is Alex, I just got my first gun, not so much for self defense but, what happened was a buddy of mine took me to the range one day and let me shoot his G27, and I just though it was a Ball. So I picked up a G23 because I wanted something a little bigger, and in the same caliber, but not quite full size. I'll be taking the 23 to the range for the first time tomorrow I do however have a few questions (a few good stupid ones too) I guess, for my first question, I'm a car guy, and I love tuning and customizing my cars, so it would only make sense for me to want to do the same to my gun I've been doing some looking and there's all kinds of "upgrades" and accessories for these things and it looks kinda neat but... I have also read somewhere that glocks being great guns and all dont take too well to "upgrades".. things like the gun going off two or three times (or even unloading the mag) can happen if you try to change the trigger and I found one neato thing that might help with the .40 S&W "snap" being a recoil spring upgrade but someone told me that can cause the gun to jam if the new spring makes the reload action too fast. So I guess my real question is can you guys tell this n00b what some good upgrades would be vs some bad ones? My next question runs into that "stupid question" category that I spoke of before .... annnnnd.... are there any earbud style (or over ear) headphones that will cancel out enough noise to be used as ear protection inside an indoor range? lol sorry I know it's a STUPID question, but i'm a stupid kid who may not mind rockin out a bit while I drop a few mags *puts on flame retardant suit* One last question, even though I got this gun 90% for the range I plan on getting my CHL really just because I can (that and transporting it will become easier) What i wanted to know was A: how well does this gun "conceal" And B: is really for any carry guys here in texas, how stingy are austin cops about "printing" because like I said T-SHIRTS lol there will be printing, at least a little while bending over, I mean, do people really have a **** fit if they catch a little peek of the handle or something stupid like that?
