It is now only available through FA for FA products. I have several and have never had a problem with them. I use only the Lovell & the TSOB on my "serious" handguns. The TSOB is an excellent mount but IMHO the Lovell is more attractive.
It's more important where you hit 'em, than what you hit 'em with.
I found an old FA 97 review that refered to the mount as a Lovell Precision mount. But can't find any contact number or website. I'll try to call FA Monday and get the scoop.
