Newbie question.....What is the difference between the number 10, number 11 and the 209 caps?  I recently bought a reproduction boot pistol that is supposed to take an #11 cap - it didn't!  The nipple was too large.  Are the #10's larger?  And what about the #209's?

IIRC, the #10 are also called 'musket caps' and are several times larger than #11.

Most muzzleloaders use #11 caps which are small, about 4mm in diameter.

209 is simply a shotgun primer.  I just bought a Thompson Contender muzzleloader which uses 209 primers.  They tend to be the most reliable of the three commonly available primers for muzzleloaders.  

I have a Ruger M77/50 muzzleloader that I still can't get to be 100% reliable with a #11 or #10 cap.  You can change the type of cap it uses with a conversion kit.  I recently bought a 209 kit for it so we'll see if it is 100% reliable.

Your pistol likely takes #10's.

#10's are smaller than #11's, musket caps are listed as musket caps. Cabela's has them.

Sorry, I thought #10's were musket caps.  But even the #11's were too big so maybe he should still try the musket caps.  Damn, I can't imagine a smaller cap than #11's.  They're already small to begin with.

I on occasion get some slightly oversize  Nipples.  They have only been a few thousanths over and I usually take some emery cloth and lightly sand them with the cloth. I like to have my caps really snug so that I have to seat them with my thumb anyways so this usually works out well. I have also found that the #11 (RWS I think) German cap if I recall runs a little more snug than the CCI #11.

#11, musket caps and 209 primers each have specificaly designed nipples/breach plugs.  To change from a #11 to a 209 you would have to replace your breach plug designed for #11s and replace it with one designed for 209 primers.  In adition the striker/hammer for a #11 is flat and would have to be changed to the firing pin type used to strike the center of the 209 primer.

I don't think you are going to find any conversion nipples to accomodate anything else for a hand gun.
