If you've got a MKIII 22/45 (one piece lower version with non-replaceable grips), this Volquartsen unit is a great upgrade. Not only is the trigger much better, it also allows you to use 1911-style grip panels of your choice (a bit of fitting might be required to clear the Ruger-style controls). It also provides an easy-to-use shim kit, so you can adjust to get a snug (but not overly tight) press fit between the Ruger upper and Volquartsen lower.

No, not exactly cheap - but well worth it and I wish I had done this years ago.

Works with other Ruger uppers, but not all - so make sure your's is on the list before ordering.

I've been roll crimping revolver reloads since forever, but I figured I would give this a try. It doesn't represent the nicest machining work (it's a bit rough on the inside), but maybe that doesn't matter for the die's purpose.

In any event, it works. I've run .38 and .357 target loads, keeping the same unfired cartridge in a 7-shot cylinder while I fired the other 6 rounds. After the 24 rounds, there was no pullet pull on the unfired cartridge. Of course, the expander die has a lot to do with this. Too much expansion and no amount of crimp - roll, taper or otherwise - will keep the bullet in place.

Two nice benefits: Length of the brass is far less important than with a roll crimp. And, since you're working the brass less, splits at the case mouth should be less frequent.

I haven't tried it with magnum loads using slow powder. This may still require a heavy roll crimp.
