IShot it several times at my friend’s place in the country. Shot Win PDX1 Defender 45 Colt 225 Gr yesterday, 410 Critical Defense other times, Hornady 45 Long Colt HP as well. A lot of power in a small package! Going to order 357 Mag & 22 Mag barrels as soon as I can. Thanks for making a great product! The BEST thing I can say is: ” Made in the USA “! It shows!
