These sight pushers used to be made by a company called "Sight-Tool" and evidently they folded but sold the design to a company called "4 x 4 Machine".
Sold on eBay by 4 x 4 for around $60 and on Amazon for around $80.
They get lots of good reviews.
I need a universal sight pusher to install night sights on some non-Glock pistols. Wheeler's a tad $$ and don't trust the Nc Star.
So does anyone own one of these and if so your experience? Is there a similar type pusher (not the ones with all the little blocks) that's just as good or better?
ETA: my only beef with this tool is that the pusher block itself is supposedly made of aluminum and not steel. A couple of Amazon purchasers reported the block got indented but they also said that D & D supplied them with a replacement block free of charge.
A red anodized version of this tool is also available from Amazon from "Washington Gun Works".
