I'm a new RM380 owner. I love this little gun! I've got a question about it, though.

When racking the slide back, the hammer cocks back with it. It looks like the hammer is making constant contact with the firing pin when the slide slams forward and chambers a round. What keeps the hammer from striking the pin with enough force to fire the round, when it comes all the way forward? It doesn't, but seems like it could.

I thought about this the first time I loaded it 6+1. I typically lock the slide back, point the muzzle down and drop a round in the chamber, then release the slide. Then I insert the magazine. The question also applies when loading the chamber from the magazine.

Most pistols have a firing pin block like this one that only lets the firing pin move if the trigger is pulled. If you aren’t pulling the trigger, it’s blocking the firing pin from hitting the primer. When you pull the trigger, the block moves out of the way so the firing pin can move forward and hit the primer.

Thanks, Cokeman, but the Remington doesn't look like that. From what I can see, the RM380 doesn't have a visible FP block. I found this little blurb in a gun review:

"It should be noted that there are no external safeties on the RM380, and there is no internal drop safety either, except for a passive block within the slide. However, according to Remington, the RM380 has been tested using S.A.A.M.I. Jar-Off, Drop, and Rotation test criteria and passed, so it is safe to carry with a live round in the chamber."

That "passive block within the slide" must be the answer, but I don't see anything in the slide that would block the FP. I'm not concerned about dropping it. This is more curiosity on my part, than fear. As near as I can tell, the hammer rides the firing pin all the way to battery, so why doesn't it fire when the slide comes forward? This little mystery intrigues me.

I posed this question to Remington. This was their reply:

"There are a variety of safety features on the RM380 that prevent the occurrence that you have described. One is the disconnector which prevents the trigger bar from engaging the hammer unless the slide is completely in battery. Another is the heavy weight firing pin spring which will not allow the firing pin to travel forward unless it is a full strike. This is similar to the 1911 series 70 design."

I love the two tone RM, by the way.
