On par with Weihrauch......i didnt!
The internal plastic cross section guide rod wears and bends and needs replacing to realise full performance but its intergral to the end cap and needs a skilled machinist to sort.
I used Delrin machined to a nice running fit instead of tight like stock.
I found the angled breech caused the breech seal to play up as it constantly tried to cant over slightly more on one side than the other due to the angle of the mating faces, eventually leading to failure.
Trigger average and the cocking stirrup failing on me after approx 5000 rounds.
In comparison, the 45s guide is much more solid and relaible but also easily swaps out for custom guides which cannot be had for the Magnum.
The breech design, with simple but much more reliable O ring is flawless.
The cocking stirrups will never fail and the trigger near match quality..
The 45 is a different class really but the Magnum did look better ....the 45 always looked a tad top heavy to me .
