I have had mine to the indoor range about 3 times now, there are about 6 of us who have Ruger MKII, MKIII, 22/45 & I have a Buckmark.
It works really well on the standard Rugers and in my Buckmark, it will work for the 22/45 with a little fiddling..... About 6 different guys have asked me where I got mine so they can order one themselves.
I have also had a few "extra" rounds fall out of the loader but it is usually the 10th round so I just put it in the mag.
All in all I am impressed with the cliploader, it was cheaper then an extra mag so it is affordable.
Cheers
