Lone Wolf Arms Compact Locking Block for 2000 - Early Gen 4 Glocks

Compact LWD locking blocks are identifiable by a dot on the left side (from shooters perspective)

Lone Wolf's Benefits

• 17-4 stainless steel billet certified materials, certs are held on file and can be traced back in the future
• Same as aerospace, very good for high stress situations
• Manufactured in a ISO 9001 facility
• Highly controlled tolerances, radiuses in critical areas
• Maximum amount of bearing surfaces since draft angles (required with MIM) are eliminated
• No surface treatment required
• 44C rockwell hardness (+/- 2) for durability 
• Greater potential for increasing shot to shot accuracy

Glock OEM parts are MIM, some problems with MIM include

• Is oversized by 20.6%, then sintered down in a mold to final size, this creates many deviations while molding
• MIM is bound by a glue. It is heated, the glue melts and then sticks together with the metal particles
