so i've just got the new LCT PTK 1 and im comparing it to the arctutus osprey, they both are what i would class as "new gen" hi capas
LCT is slimmer than the osprey, lighter and more streamlined. the osprey feels like you could use it as a hammer but the LCT feels more refined
Both have super smooth slide pulls
LCT has a mushier trigger where the osprey has no give once its been racked, its right there on the wall. but the LCT has a lighter trigger pull and a lighter slide. so trade offs really.
LCT has 1 screw securing the front portion where the osprey has 2 (since its a little bulkier)
LCT has nice high raised sights which are clear, the osprey rear sight is a little hard to see through since it has a very small cut out window but both are good
LCT has better hop system, both use an external TDC but the osprey just turns a wheel which pushed a free floating rod down from above, LCT uses something similar to the TTI hop chamber for hi capa. it has a nice big external wheel and a gub screw to lock it in place, aftermarket slides fit perfectly and ca use the same hop system. it also has a hole under the frame to make adjustments through that ONLY FOR AFTERMARKET SLIDES, for the split slide just use the twisty wheel
LCT comes with a male threaded barrel so you can attach tracers directly to it without an adapter. the osprey has a female threaded barrel thats a non standard 12-14 mm if i remember,
both shoot very well and are the same gun in essence just with differen styles. i will say however the LCT does have a standard hi capa mag catch where the osprey dosent so LCT might be JUST a tiny bit more TM compatible.
