Don't forget the 10mm for the 45. If it's a 21 or 30 you can even get a 460 Rowland conversion for it. Two guns, six cartridges! Not bad.I purchased a G36 last year and haven't carried it much. I usually carry my G27 it just feels better to me. I just realized from reading your post that with two Glocks I can have the option of 9mm, .40S&W, .357 Sig and .45. Not too bad! I think its time to go barrel shopping. Who has the best deals and service?
