Diana 280 or 34?

[Barryg]

I would leave the Diana well alone. The wife had 2 of the .177 carbines. They were a basket to cock, requiring even more effort than a gas ram. The trigger mechanism was appalling, I know people keep praising the T06, but the two I have experienced are far worse than the trigger on a 25D! They were way too light, too sensitive, basically hair triggers with no feel. Tried getting them adjusted. In the end the wife sold the rifles. They look good but are really not! She bought one, sold it, then decided to try spring guns again, bought another, found exactly the same problems, last Diana we bought and we will not buy another!

An HW95 or 99 will outshine it in trigger quality!

I was just wondering if you know much about airguns
If I had a complaint about a particular airgun I would want to know what the problem was in detail so I could explain to others, not just say its hard to cock, I would want to say it was because of the short barrel or that the linkage was wrong or it was grinding or somthing, and I would want to know why the trigger would not adjust especially when so many who know what they are talking about all over the world say that the T06 is equal to the rekord and probably better constructed.
Have you ever examined a Diana action part by part and compared it with a new HW action?
You could have just been unlucky and got two lemons like you can with all makes but you should have checked out the first 280 before buying another

I dropped one of the development springs in my .177 that me and Wonky have been working on, stock guide shortened and a tophat installed it gave 11.4fpe right off with exacts, very tight spread.

I will upload the pics i took of the piston to the blog, it shows where i machined it to round at the nose...so it will show you where to tickle it with a file to give similar results

The skirts on the pistons are seriously hard, a polish and good lube is all they really need for a nice budget tune. I do however alter the shape of the cocking arm where it rides on the spring and polish it to get that like butter feel
