We have recently received a shipment of Meprolight TRU-DOT night sights for many common pistols such as Glocks, Sigs, HK, etc.
MSRP starting at $97 which makes them very attractive if you want to update your dim night sights or standard white dots sights.
Sights shown on the left are for Glock pistols in 10mm/.45ACP, on the right they are for H&K USP Full Size, Tactical & Expert Pistols (.40, .45ACP).
