In the early days of R9 ownership, it became clear that for many, the process of takedown and reassembly was fiddly and difficult. This is mainly because to keep the gun's profile clean and slim there is no provision for a slide lock.

This means, that in order to remove or replace the main pin (across frame below ejection port), some means has to be found to hold the slide back at exactly the right position. It is possible to achieve by a strong hand grip but far easier if there is something to insert of the right size.

I discovered that a chopstick was ideal for my purposes but RJ went one better and came up with a wedge-shaped piece of soft aluminum and later a soft brass option - 3" long. This is inserted to the required level to hold slide back with pin aligned and was very popular.

The pictures below give some idea of what it is like. At the last count the aluminum version was $12 shipped, the brass $18 shipped.
