Couldn't wait till weekend, I went today to the range
So the plastic Jericho feels great in hand with full mag, recoil is felt a bit harder compared with the full metal frame one (I shot them one after another)single action trigger is definitely smoother and lighter on my full metal frame (I have 2 full metal frame ones, both have same perfectly smooth and short SA pull)
Mags from both fit each other (both tested are 9 mm).
The full metal one with full mag feels like a real gun in hand, real solid, the first shots with full mag have very low recoil, compared with the Polymer one.
Accuracy is hard to judge from my shooting as I haven't shot them at all before today, below are my targets.
First target is from the Polymer one, 5 shots from around 8 meters , second target is the full metal frame one, 5 +1 shots,
the target paper is a standart Letter size page.
and this below is from the full metal frame one.
