Our 1911 Conversion is compatible with very many other good-quality 1911 platforms. If you do not see your go-to gun listed, please consider the general criteria below.

In some cases, less-expensive 1911's may present a problem as their slides are sometimes "spot-treated". We require that the slide be fully heat-treated, as noted below, to ensure it will not deform under the pressures of the Mighty .460 Rowland®.

BASIC CRITERIA for a Successful .460 Rowland® 1911 Conversion Platform:
We recommend that you contact the manufacturer (as necessary) to confirm your gun meets our requirements:
• Modern, High-Quality, i.e. fully heat-treated slide {to Rockwell-C hardness > 36}
• Standard 5", Normally Ramped, i.e. not fully ramped,
• Standard Barrel Bushing Configuration, i.e. no bull barrels
• Not a “double-stack”….we have had very little success converting guns with DS magazines

If in doubt, many gunsmiths can do the relatively simple Rockwell Hardness test on your slide.
