Just finished up swapping the 2.0 parts into a 1.0 subcompact .40.
This time I also used a 1.0 locking block and takedown lever. Only 1.0 part is an Apex Tactical trigger installed on a 2.0 trigger bar.
The 2.0 locking lug will not fit/sit flat in the 1.0 frame due to a small bump of metal on the bottom of the locking lug. A short time with that little hobby belt sander (bench model, 1" belt) took care of that.
Attached FileThe 2.0 locking lug would drop right into position with a minimum of thumb pressure but was real bear to get out. It starts to cock sideways and hangs up badly. Took multiple tries and prying up with the punch to finally get it out so I could get the disassembly lever in the locking lug and get it all back in there. Tip - ever test fit is the same. Easy going in, tough getting it out. Zero issues with the 2.0 sear housing installation.
I did notice, this time, there was no contact between the back of the trigger and the frame notch. Don't know if the difference was the hole/notch in the frame for the trigger is longer on the subcompact frame, or whether the use of the 2.0 locking lug affected it, or if the Apex trigger was just made a little different than the one used for the 5" 9MM pistol. The parts went right in.
Safety worked, pencil test was positive, trigger feels lighter than it measures. Measures out at just under 5 lbs. I let my wife dry fire it and she thought it had a nice trigger pull (nice and crisp can fool you on trigger pull weight/force required to release the hammer/striker).
Now to get to the range and shoot it some more. For me this was worth it. For one thing the trigger is much nicer than the 1.0 trigger feel/pull. And I can add to the store of 2.0 parts and use them in the 1.0 guns as well as the 2.0 guns.
