Heinie magwell, Morris custom or Tech well system

[Rye956]

I am in the process of building a single stack pistol that I will use for Single stack div. I don't have any experience on any single stack magwell that works well with single stack division. Need some input and advice as what to go for. Thanks.

I use a Techwell on my 1911 9mm in IDPA ESP and USPSA SS.
