Ball gun sights

Post by donp on Thu Jun 30, 2016 8:26 pm

Hello all. I am wanting to make a ballgun out of one of my 1911 pistols. It has an Springfield Armory Milspec slide. Are there any adjustable rear sights that fit the factory dovetail? Any info on what is typically installed on a ballgun is much appreciated. Thanks. Don

best bet is to have a smith cut the slide for Bomar style rear and a dovetail front. that will give you the best sights going.


LPA does make a adjustable rear sight that will work with the factory front sight  and a standard rear cut.

Brownells carries them..

Go with LPA gives you a longer sight radius, check with KC Crawford.

I just installed the LPA SPR (SPR45CT07) sights on a Rock Island slide a couple of days ago.  The rear sight took some fitting and the front requires the use of a staking tool for installation.

The set was about $100 from ebay.

Rock Island is in their own world with their cuts

The skinny is that the SA mil spec uses a colt/gi cut. It is neither a Novak or a Bomar cut. The good news is that they make a sight that will work with your existing front sight. The bad news is that even knowing the cut you have several choices. The blade is either .322 wide or .330 wide. And you can have a choice of black, dotted or outlined. The sight shown here fits the .330 and is black. Read all the info on the bottom and it will explain better. Hope this helps.   http://www.ebay.com/itm/Colt-Gov-1911-A1-Rear-Adjustable-Sight-Black-Serrated-/251955997052?hash=item3aa9bf697c:g:kHAAAOSweW5VULNM

I used a bomar clone on my Springfield.  It was an STI. Required some fitting including filing a small flat on the top of the slide. You'll need a taller front sight, too.
