^^^^^This^^^^^

I've run CCI Standard through my X Trim Whisper with no problems like the O.P. with the weaker spring. Worked flawlessly, and the moderator reduced the pop considerably. Managed some subs fine too, though you could tell the pistol was on its limit with regards to ammo as the slides recoil became a little sluggish.

You will love the extended mag, I used my two tonight and they ran perfectly.

You got a hell of a birthday present!

Hi Can you please tell me which make of subs you were using as i am trying to find a make that will feed ok Thanks Paul.

Was a while ago but if I recall correctly, they were Winchester subs.

My gun came with a strong recoil spring and a weaker one. I had to run with the weaker spring and the recoil was sluggish and not snappy though the pistol did feed and fire them.

Hi I took the pistol up to the tunnels shooting range over the weekend which gave me the opportunity to to give the pistol a good work out. Again I found the pistol shot well with CCI mini mags and other standard velocity ammo. Anyway 300 Rounds later, time to try the subs again. First the Winchester sub which gave intermittent reliability, then Eley subs same again, then CCI subs same again. Time to change to the low power spring, unfortunately could not get the inner mod tube off the barrell, it was stuck solid, so was unable to try the low power springs. Back at home I had to take a blowtorch to the inner mod tube to remove it, as it was full of crud. I think I will have to clean the internals of the mod after every 50 rounds or so. Back up to the tunnels next week to try out the low power springs. Many thanks for your reply Thanks Paul.

To make cleaning easier I use a small amount of bearing grease on the inside of the mod end caps where they slip over the barrel, and a small amount on the muzzle thread (and I do mean a small amount). Helps removing those caps a lot easier after firing.

As for the inner mod tube, I ditched that, the spring, and the washer. I use a tube consisting of fine bronze mesh (roughly 150 holes per inch or finer) rolled several times over the ported portion of the barrel which I have small zip ties holding it together. Hard to explain (I'll take a pic at some point), but I personally think it's more effective than the original design and makes the gun easier to clean. Many older mod/suppressor designs used mesh so it's not a new idea.

The later whispers don't use an inner tube etc at all, the barrel is ported only just back from the muzzle and the whole mod body works as a big expansion chamber in a similar manner to a reflex mod. Pics of both older and newer whisper mod guts are in Airbrushes and my own posts one or two pages back in this thread.

Hi I now have had time to look at the pictures of the 2 versions of the whisper barrels it seems that having only got mine a week ago I have the older version. Thanks for your reply Paul.

Just an update on my sticking Mag problem.

I took the Mag apart, quite easy just tap out the pin on the base.
Apart from the spring and the pin, all the parts are plastic.

I found that the two buttons you hold to pull down the spring to load ammo is made of round plastic in the middle.
This was rubbing against the body of the Mag & wearing a grove into it.
I used a small fine file to rub down the inside of the body of the Mag & to try & round off the button again in the middle.
Stretched the spring very slightly, cleaned it all off & reassembled.

The Mag is no longer sticking & appears to be working properly again.

How long it lasts though, before it does it again?

Will have to contact Caledonia Classic Arms to see if they sell replacement internals for the Mags.

To be honest I bought two of the 19 round extended mags and never looked back. Trying to find a couple more so I can toss the 10 rounders in the bin or set fire to them depending on how my mood will be when the time comes. I've had so many problems with them and hate them that much.

The 13 and 19 round magazines are far better, made of different and more sturdy plastic. No idea why they went to the 10 rounders but I suspect penny pinching.

Shame as it's a well made gun and great with decent mags.
