V-Lock Retainer Spring

Having issues with the Bolt Stop Cross Pin walking out of your MK IV frame during heavy use? Our all new V-Lock Retainer Spring provides positive retention of the pin so that it can't drift out on it's own, but without impacting your ability to take apart the pistol.

• Replaces part # 41 on the Ruger MK IV and part # 37 on the Ruger MK IV 22/45
• The hammer will need to be removed from your pistol in order to install this part

• Made in the USA
