Quote from: Flex on March 27, 2024, 03:07:08 PMWell, I agree that this is an interesting situation. I took measurements of my older 1377 (2nd variant), 1377c, 1322c, 2289 (BackPacker) and 2240 (backbred to .177cal) and found that all of the tube diameters were very similar to the measurements that you obtained (perhaps a few hundredths of a mm different). The diameter of the steel breeches on each (except for the 1377(2nd variant) that is still with its OEM breech) all measure ~18.88 (+/- a few hundredths) mm. You didn't post the diameters of yours but I would imagine that the measurements would be similar. Are the steel breeches that you bought an actual Crosman product? I.E. made in the USA and imported to Europe or manufactured elsewhere? That may be the issue.A quick postscript. A discussion on the Gateway to Airguns forum, dealt with this issue. The reply stated that the Crosman breeches are made to fit the tube on the 2240 (and the others with the same diameter tube) but that they will fit the 13xx series. The issues that you are experiencing is mentioned with the fit on the 13xx series pumpers. The post was from just over two years ago. Why the breeches on my airguns seem to fit better is still a mystery.
I was wondering if, in fact, there's a different breech for the 1377? I can't imagine that though since the tube diameters for the 1377 & 1322 are the same. If a product is said to fit models 2240, 2260 & 1322, it should also fit on model 1377.
As I said at the beginning of this reply, "this is an interesting situation".

Perhaps it should be worded "click here to attach photos" as doing so opens a small window offering the photo library or camera. I chose the library as I already had the photos. After I chose my photos and clicked on "add" I learned that there was a size limitation of 500kb. That might be common knowledge to others but I either didn't know that or possibly forgot. Anyway, I don't want to sound "snarky" but better instructions might be helpful to others too!
