Thanks for the comments guy's. The Husqvarna M40 (Lahti) is an interesting gun. Aimo Lahti was a top gun designer in Finnland sarting in 1921. His stats are here Aimo Lahti - Wikipedia, the free encyclopedia
. I wanted one of these "poor man" Lugers for a number of years and in 2012 I finaly didn't get hurt too badly on GB with paying about $500 total for the one you see. The first model was the Finnish made L35 and are crazy hi in value these days. When I first started looking into the much cheaper Swedish made M40 about 5 years ago, they were running $350- $450 for decent shape ones and now those prices are long gone. The early M40 has a bit of a bad rep for cracking slides due to war time scarcity (cost) of good metal, they used a poorer quality for a number of years of production. This problem was finally remedied with a redesigned slide. Here I have pictured an outward raised rib that was added on the left side for more strength and these newer slides were apparently made with the proper steel. The refit of the newer slides on the existing inventory of military and police arms was thought to have been in the early 60's. But by then the M40 was being dropped from service. I have seen several older left side flat recievered guns for sale on GB and folks think they are as good as any but they are not. Here is the rib circled.
As you can see, Lahti took the Luger design and simplified it to the point where it would be far more reliable in Sevier winter weather. My M40 is the less common small ring "police" trigger guard where as the picture above shows the larger & beefier military contract trigger guard. The Luger is far more compact and lighter since these guns run about 2.75 lbs unloaded but they are fairly accurate shooters. Sarco originaly had about all the parts that were imported and Numrich bought a crap load of M40 parts off them at some point. I picked up a brand new upper receiver assembly with complete bolt from Numrich back in 2012 when I got the gun for under $200 bucks. They still have a lot of parts (under Lahti) but those recievers are long gone now. I bought an 9mm barrel that I was going to make a long barrel Artilery top end since the gun is cut for the Luger shoulder stock. But like a dozen other projects, its still waiting for me to piece it together...... If I ever get it done, you guys will see it here.
