The overall fit and finish of my gun is beautiful. However, and I didn't notice it so much when I bought the gun, but the slide sticks out beyond both sides of the top strap more so than my later 5 1/2 inch heavy barrel Model 41. I'm un-equiped to supply pictures at this time or would. I'm wondering if this may be a replacement slide. Were the dimensions of the early Model 41's top strap narrower than later models? Or, did the width of the slides vary between early and later production guns? As you can tell I'm relatively inexperienced with Model 41s.
