The caps have landed. Fit is just about perfect. Takes just a tiny bit of effort to remove so it shouldn't fall off in your bag or pocket. The Workhorse can be fired with the cap installed. So, you don't even really need to remove the cap to use the
mod while out and about. I don't think accidental firing would happen unless the perfect storm of circumstances occurred.
Now I just need 11 more recessed button 22mm mods.
