This pistol had a magazine disconnector built into the mainspring housing. I removed it from my own pistol as I believe it to be superfluous. It now works perfectly without said mag disconnector. No, I don't need it as a "safety." It is a range toy, nothing more. It is already a Series 80 design and I am somewhat experienced with 1911 pistols, so I find it quite safe without this moderately annoying feature.

By the way, I was able to get several extra magazines in SIG-SAUER packaging when my son's store had an overstock sale.  (As noted before the SIG .22 is simply a GSG with SIG markings, so the magazines are obviously identical).  I must have at least six for it now.  This is a nice pistol.

Image Info: German Sport Guns 1911 .22.  Based on reviews this seems like the best 1911 in .22 that looks and works like a 1911.  GSG also makes the 1911 .22 for SIG SAUER.
