Ok, this is not new. The military has been doing it for some time. But, for the benefit of those who did not know, you can quite easily modify a Beretta 92FS for your Sig P226/8/9. (see the picture). Tools: Dremel, cold blue paste Time: ~ 20 minutes skills: steady hand and good eyes sight * In the pic, I referenced the location from the Beretta holes. But, if you already have Sig mags, I'd recommend you double check. * You do not need to dremel off holes on both sides, unless you also plan to use it on a lefty Sig. I found that out after I did the hole.
