Ok, just my .02 cents worth. As far as caliber goes, it really is up to you....9mm is popular and cheaper, but some people prefer the larger calibers for "knockdown power".(this is an argument for another time) Glocks are good guns, durable and reliable.I have and still own many andI enjoy shooting and carrying them.2 questions, why are you limp-wristing a glock, and why do you find them boring?
Iown a SA XD, but I am not a big fan of the lemon squeezer. I hardly every carry or shoot it, and it has been in the safe so long, it may be permanently "welded" to the rack. They are way too big in my opinion, more like holding a drill than a gun.
1911s are great, but not for everyone. I have several. S&Ws, SA,Kimber,Colt. All nice, but not the most simple firearm ever made. They are also heavy, bulky things, unlike the polymers listed above.They require alot of shooting,attention and shooting. You can get them in 9mm, 10mm, and 38 super.
One thing I will mention, you say you want American.....Have youconsidered a Smith & Wesson M&P? Great guns, great shooting.Take a look at them.....
