Decided to trade in my Mark 3 on a New Mark 4 lite with threaded barrel so I could run my spikes suppressor. The new takedown procedure was a factor, the old models were a real pia

i kept my mkII but love the new mk4 as well

I made the same move. Was never taken with the Mk III. The Mk IIs were much better than their replacements. So far the Mk IV has been great and the takedown is a plus.

I thought about keeping the 3, however I don't really need it and nobody else wanted it, plus, wasn't threaded for the suppressor.

Final nail in the 3 was last time I cleaned it the damn thing was a PIA to put back together, Yeah I've done it plenty of times but the thing wouldn't go back together correctly, and it was difficult to disassemble, got tired of screwing with a stupid designed system where you have to stand on your head juggling the firearm upside down while drinking a glass of water...

New one is Push Button take apart...

Will get it to the range and see how she does...

I, too, went from an MK III to an MK IV and haven’t looked back. The ease of maintenance was a huge seller for me. There were a couple times where I knew I was doing it correctly but the MK III just didn’t want to snap back together. Definitely glad I gave the MK IV a chance.

Just pick up a Mark IV lite. Fun plinker. Like you, the new take down is fantastic compared to the old marks.
