PM9 is 9mm, Long Beach Operator is 45acp
first time shooting the PM9. I've had the Operator for a few years. shooting the PM 9 for 70 rounds, no failures no hiccups, ran perfect out of the box. the Springfield is just as reliable
testing the 2 bc these are the best 1911's that I have. I can't afford a Nighthawk Custom or Wilson Combat, so these 2 mid tier/upper tier production 1911's are what I can afford. like most of us, I assume.
In the comparison I consider reliability, trigger, sights, accuracy, shootability, features that come with the pistol, and overall fit and finish/build quality
trigger on the PM9 is 2 lbs 12.9 oz, on the Operator it's 3 lbs 6.7 oz. 13.6 oz difference. pretty negligible. both feel great
PM9 has fiber optic front sight, adjustable target rear sight. Operator has Trijicon tritium night sights front and rear. just depends what your needs are. neither is better, just they have a specific purpose
accuracy is negligible as far as I can tell from shooting them both off hand
both shoot great. triggers are great. no issues with both having any failures or hiccups whatsoever. back on target a little faster with the PM9 bc it's 9mm, so that's the caliber not the gun
the features that differentiate between the 2 are. the PM 9 has front checkering on the front strap, has grooves on the top if the gun to cut down on glare. Springfield has a magwell which I really like much easier to load mags with the magwell, and rail for lights etc. other than already mentioned, pretty similar
the one thing about the Springfield is it is tight tolerance slide to frame and it's a little difficult to rack the slide which should improve as I shoot it more. whereas trhe PM 9 is also tight tolerance but racking the slide is easy, very smooth out of the box. not a big deal at all.
overall fit and finish goes to the Dan Wesson by a slight margin. both are very well put together. its just that the Dan Wesson feels a little smoother. slight edge to Dan Wesson
IMO, which one is better? can't really say. either one is a great choice. for a duty/defensive 1911 I would go with the Springfield. for a range/target/competition 1911 I would go with the Dan Wesson. just depends what your needs or wants are.

I shoot the Dan Wesson first in the vid
