Mine...
I was shopping for a conversion when everyone else was - literally. At the time, Spike's wasn't accepting orders for rimfire parts, and every conversion known to man was backordered.
I ordered some new parts, and used a bunch of take-offs to rebuild what was left of my first pistol, an AMT Hardballer, into a dedicated host. After my frame was finished, I ended going from wanting a Marvel conversion to wanting
a conversion. The first one I found in stock anywhere was Brownells, a fixed sight Ciener.
Despite his reputation, he built a quality product. So I went ahead an ordered it. POI was a little high out of the box, so I filed the rear sight down. All said and done, the rear notch was about .050" deep. Different lot of ammo, and POI was high again.
So I dropped it off at the 'smith for something I should have held out for - adjustable sights. He mentioned having a used bomar or LPA in the shop he'd cut me a deal on, so I filled out the work order and left it with him. He milled as deep as he could, but when all was said and done, it shot high with the rear sight bottomed out. So, I ordered a Novak blank, shaped it to my liking, and dropped it off again.
Total cost, including purchase, rebuild, conversion kit, and modifications, about $850... And I'm not finished yet. I shoot high-thumb, and most, if not all of my malfunctions are do to my thumb dragging the slide. I'm planning on adding EGW thumb guards or a Swenson safety, the EGW parts will be less expensive, but easy has value... Since I pay someone else to mow my yard, I'll probably end up with the Swenson Safety.
Comparing a factory built rimfire 1911 to a Marvel is like comparing a RIA to a Wilson... Before you flame me, consider the fact I plan on adding a RIA to my collection - and while I have handled and fired a few, I don't own a Wilson.
If you get one of the
better conversions, you can use it on one of your 1911s for the time being, and build up a 1911 frame later, or spread the lower build out over a few paychecks (I did this with my AR22).
