2 Gen 3 Glock 21

Somewhere somebody said that if you find something you truly like, buy multiples. I think owning a back-up of an often used gun is probably more practical than most would suspect; I shoot IDPA and carry my IDPA gun but if anything would ever happen from a catastrophic breakdown or if I just wanted to send it off to have different sights installed I can grab the back up and seamlessly blend right back in to where I left off.
Of course, from pistols, shotguns, 10/22s, Garands, M1AS, AKs and ARs.... I have alot of variety but also have some equipped exactly alike for full family familiarity...
2 'Artillery Model' 1873 Single Action Army revolvers in .45 Colt. One in each hand shootin' full load blackpowder rounds. An' if'n I miss, I'll gas 'em to death!
