Sight base screw for a PC 40

I have a Ruger PC 40 with the rear peep sight. I need a few replacement sight base screws. Does anybody know the size of the screws? A phone call to Ruger Customer Service did not yield any results.

I am assuming you mean the PC4GR (.40 S&W) carbine (with the ghost ring sight). If so here is the Ruger info: Ghost Ring Sight Base Screw, 2 Req'd G06401 PC9GR, PC4GR

I checked www.gunpartscorp.com and they don't have any and doesn't show any tech data on them.

Sorry.

aren't they 6-48 or maybe 6-40 tpi, just get any of the Weaver style scope base screws they come in all lengths and head shapes..........
