I changed your message to use the "link" rather than "url" function. "url" doesn't work.
The response above is talking about removing the safety while doing a detail strip the gun, NOT to leave it off.
If your intent it to take it off and leave it off, I'm pretty sure it won't work -- but since you know how to go about it, why not try?
(I think both sides of the safety are needed to hold the assembly in proper alignment; with one part gone it probably won't work right.)
