Congrats, another fine looking Reo! Most people like the Grand but I love my Mini 2.1 just as much!
The delrin button covers, they do make firing feel easier. Some say with the covers it's very easy to rotate the switch into the locked position & can happen unwillingly. I did experience that once but after I retensioned the firing pin I never had that problem again.
I used to use the button covers....up until a few weeks ago when I let an old friend try out my Grand with a delrin cover. The button rotated into the lock position when he grabbed it, went to fire it, & mashed on the button. The button got pushed all the way down to the top of the body while in the locked position.
I had to go to the truck & use a razor blade to pry it back up. I never ever had a problem like that when I used them. So just keep that in mind if you ever let someone try your Reo, make sure it's not in the locked position, & advise them not to press really hard. From that moment on I removed the button cover & never used them again.
I made a couple of brass button covers with that in mind. Never did mention it to the lucky two that got those buttons but I machined a shallower hole so the buttons can't be mashed down too far causing the button to be inoperable. If anyone does have that issue, the same can be achieved by installing an appropriate washer or shim in the hole (you'll have to do some measuring though to find out what's ideal).
I only liked to use the button cover on the Grand. on my Mini 2.1 I modified the stock button with a chamfer on top. Since that incident with the button cover, now all my Reos sport the modified buttons. Just my preference now but the delrin button covers are great.
