Hello All,

I am purchasing a Spanish 12g SxS Sidelock shotgun, probably made in the 1970s, with Armeria Pardo S.A on the side plates, but with IRU as the gunsmith's mark.

Here is the link to the shotgun that will be arriving next week: GunBoards Shotgun forum- link to Armeria Pardo SA IRU SxS

I would appreciate any further information, beyond what is in that thread, that would help me to:
remove the stock
clean it properly
maintain it [type of ammo to use/avoid?]
anything else you can share.

Looking closely at the higher quality pictures that were went to me, it appears to be a 5-pin action design, and the location of the pins looks just like the Grulla Elite 216RL at this link: Hallowell Company fine shotguns- Grulla 216RL SxS
I am linking this ONLY for visual comparisons- I am NOT advocating for any purchases [or against any purchases].


From my research, it appears that I need to [using the Brownell's flat-ground european thin-blade screw tips I bought] remove the two screws that have slots in them, and then tap the receiver until the sideplate 'lifts' a bit, so that I can then pull it out [gently].


However, I have heard about 'captured' vs 'uncaptured' actions- and have concerns.

Do these shotguns work as I described?
Or, when I begin to pull the side plates off, will the entire action fall apart into a pile of loose parts?

I haven't taken a sidelock action apart so far.
I have disassembled a boxlock before [JP Sauer].
I have disassembled the Cimarron 1878 Coach Hammer lock action [which I think is kind of like the sidelock, but different?]


I am just looking for any tips that can keep me from botching it.

I have watched the MidwayUSA or Brownells [I forget which] youTube video of disassembling a SxS shotgun.

I am pretty darned mechanically inclined. The list of all the different firearms I've detail stripped and/or done trigger/action jobs to totals over 40, and includes SA and DA/SA revolvers; Striker-fired, SA and DA/SA autoloading handguns; Lever/pump/bolt/semi-auto rifles; Pump, semi-auto and two break-action shotguns.

I am not trying to 'toot my own horn'. I understand the reality that you don't know me. I also understand that the 'normal' advice in that situation is simply to have a qualified gunsmith do it for me.

I LIKE doing this- just like working on cars, motorcycles, computers, stereos, and the lathe. I want to learn how. My experiences make me confident I can do a safe job.

However, I am not familiar with the design- and could use any tips you can share regarding the way it works.

Thank you


Classic 'field' SxS's are what draw me in- that way I can have more than one!
