Here is one of mine showing the 5" heavy target bbl. (might be 5.5", can't remember) & the rarely seen light weight "Field Barrel". The latter with its red front sight insert gets the most range and field time but is rarely out of the safe truth be told.
The long bbl'd 41 belongs to my #1 son, who left it with me for safe keeping as he didn't have his own safe. I've spent some time with it, alternating it with my shorter model and found it no more accurate, and in fact a bit wobbly with that 2" longer tube. I'd expected to see some improvement in my scores with the longer sight radius...but it just didn't work out.
Alert: Geezer History...Back in the mid-70's, I shot in the Connecticut .22 cal., 50' Bullseye league for a few winters and at that time, the Hi-Standard "Victor" was the top dog among most shooters in the league, even the Colt factory team was using them vs. their target grade Woodsmens. I did fairly well with the Victor, but never really warmed up to the grip angle.
So after a brief range session with a friend's Smith M-41, I was sure the grip angle felt better and would make a difference; the Smith was going to take me up a level in my shooting...
I promptly bought one from Lyman's famous Blue Trail Range Gun Shop and started practicing...Well, it was all for naught, as my scores didn't improve whatsoever and in the end, I kept the 41 & sold off the "Victor" went to another team member for what I had in it.
Over the years, my only gripe about the M-41, at least for casual carry afoot over field and meadow (with the original factory grips), is that the mag release button is just too easy to inadvertently release...it frequently got bumped on the holster for my right handed OWB, 4:00 carry position and I lost not one but two of those pricey Smith mags before I figured out the problem. As I rarely carried it off range, it was years before I took the time to make up a good, workable holster for it.
Mine was and still is 99% reliable, even with Remington .22 plastic box target rounds from back in the day, & even with US Military white box standard vel. stuff. Nowadays, I shoot mostly CCI Standard, & it's 100% or nearly so.
Here are some pics...the 1st with both guns; (mine wearing the field bbl. and my son's with the 7-1/2" tube). The 2nd has another view of the slender, dare I say elegant, field bbl. profile. And the last is my gun with the field bbl. and one of my holsters, rebated to avoid the mag button interference problem. Best regards, Rod
