Re: 2245 mods??
Yes. This is an easy modification. One DYI or $10-$20 bushing and half an hour will do it (you only need the bushing; your MK III hammer will work fine).
Look on the Rimfirecentral.com and guntalk-online.com forums - they list options and have detailed pictures, links to videos. Mags drop free when you push the mag release once done. Also gets rid of the mag in, mag out, mag in, mag out, dance at reassembly.
A Google search for 22/45 bushing will also bring up videos, info.
This does remove a factory 'Safety feature', so be aware that after the mod it will fire with the mag out and of any potential legal/warranty consequences.
