Don't blame you for wanting to do a little homework on this M/L. I do the same. Do a search on this forum to see past posts on this M/L. Sorry to say that they are odd. The hammer and nipple are not conventional. I figure that vents are there so you cannot over pressure on heavy loads. I might still have a manual but will have to do some looking. If you are having mechanical problems, arcticap has a great suggestion and the folks at TC surely will help you out. Don't phone them, just send your pistol in at the address you will find in their website. Make sure you include a list of problems in the box.
Be Safe !!!
