if you like glocks check out the model 21. 13rd 45acp. dont know if you have expirience with glocks or not but since you mentioned them i thought id pass that on..though its a littttle large for CC..its full sized..could carry it if you wanted..dad just bought a 21 and he loves it. i dont know that i liked it..grip was pretty wide for me but shoots well..also check out other 45s. see what fits your hand and what you like. i personally like sig sauers glocks and kimber 1911s but thats me. id definently probably stick with a 45. ammo is generally readily available and it packs its punch.
