If it is as you describe, the lock is not an island type. Many call the more common touching locks "peninsula" locks, for obvious reason.

Island locks most commonly are found on Purdey guns and rifles, such as this one.



Here is what would be called a peninsula lock on this Alex. Henry.



Both of the above are back action locks because the mainspring is behind the hammer.

This Charles Daly is an example of a bar action lock, with the mainspring located in front of the hammer and nestled in the bar.



I hope this helps.
