45 Acp Back Up.From the first touch you know you have quality in your hand. 45 Auto is no problem in this little cannon.Got the 3 inch barrel for 45/410 at half price (Blazebond.com), weather sucks,still waiting to try.Everybody at the company Christmas party loved shooting it,and wanted to know where to get one.2 1/2 ” 45 barrel is amazingly accurate.So far I love it and will definitely buy more of your products.Driving holster is great,still waiting for my shirt and hat(status processing). Five Stars, Two thumbs up, etc.
