Nice quality, but tight fit. - Volquartsen Firearms Ruger MK IV Pistol Magazine Base Pads

I bought 10 of these to upgrade and convert a couple of 22/45 magazines. The quality is outstanding, however it was a very tight fit to slide them on to the magazine. I used a little gun oil in the groves that the magazine slides into. Additionally, to make it easier I used a rubber mallet to tap them into place. I hope I never have to attempt to remove them.
