I'm posting this here because I'm not sure how many people check out equipment reviews. Garands are great fun and despite all the AR stuff out there I would not feel out gunned if it was my battle rifle. And most everyone who owns one knows about the famous "Garand thumb" It's not all that hard to manage one but one slip up and you'll know what I mean....lol. Well....after over 50 years working construction and having pretty severe Arthritis I found at times I was better off holding the bolt back with my left hand while I inserted the enbloc clip.
Awhile ago I came across a device called the Holbrook device developed by Mr. Holbrook. It slips into the rifle in about two minutes and doesn't permanently change the rifle....you can restore it to original in two minutes. What the device does is to lock the bolt back after the last round is fired. The you manually eject the enbloc. Then ram a new one home and pull back on the bolt and release it. No danger of your thumb being whacked. It works very well and really doesn't slow things down a bit. I like it and like I mentioned if you're plagued by nasty Arthritis you may want to take a look at getting one.
