Looks like a good quality product but,.... - Pachmayr Competition Speed Loader 5-Shot S&W J Frame/Ruger LCR, Ruger SP101/Taurus 85/ Rossi 68

This said it would fit a SP101 and it did not. Your experience may vary but, it didn't work for me. I got Safariland speed comp 1 and they fit perfect. I tried and tried again but to no avail. I have Pachmayr diamond grips, they did not get in the way, this does have a very slim profile which is why I got them in the first place. Optics Planet did take care of the issue so if you want to try them get them here and if it doesn't work at least you got it from a good company that will help fix your problem.
