Quick question.. I changed barrels on my Mk1 pistol.. Now the trigger pull seems extra long.. did I do something when I took the mainspring out or seat the hammer wrong? It shoots fine but just seems longer...Any help is appreciated..
Looking at your question I must say I cannot envision a scenario where simply changing the receiver would impact the length of the trigger pull, as long as you did not change or adjust anything internal to the frame. The hammer, sear, disconnector, and frame housing all being from the earlier pistol are still exactly the same. If the hammer drops and resets the mainspring housing is installed and operating correctly.
