I looked more closely and you were right, the width is a little bit more on the replacement. So I broke out the dremmel and voila! Thanks for you help, and the video. You're right they don't put a lot of craftsmanship and I've read the hardened steel fault with this item in the past. Thing is, at 21 this is what I could afford. I have several other revolvers but none has the 15+1 round capacity, so I like to use this to qualify for HR-218 (fed. firearms cwp). Thanks again for the help!
